SPARK-ARRESTER.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed January 28, 1907. Serial No. 354,466.

To all whom it may concern:

Be it known that I, Gus A. VoLnY, a citizen ofthe United States,residing at Wentworth, in the county of .Lake and State of South Dakota,have invented a new and useful Spark-Arrester, of which the following isa specification.

This invention relates to spark arresters for the smoke stacks oflocomotives, traction engines, and the like and its object is to providea device of this character which is simple, durable and inexpensive inconstruction and which will not interfere with the draft through thestack.

A still further object is to provide a spark arrester which willautomatically assume such a. position as to cause the wind to blow thesparks and cinders thereinto.

Vith these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

l In the accompanying drawing, which is a perspective view of the devicein position upon a stack, the preferred form of the in-- vention hasbeen shown.

Referring to the figures by characters of reference, l is a stack havingan annular flange 2 near the upper end thereof which serves to support aring 3 loosely surrouinling the stack and designed to rotate freelythereon. This ring may if desired be split as shown and provided without-turned cars 4 clamped together by means of a bolt In order toimprove the construction. of the ring it is important that the same befree to rotate upon the stack. Extending upward from the ring 3 andsecured thereto in anypreferred manner is a skeleton frame consisting ofspaced bowed wires 6 and 7 connected at their lower ends, as shown at Sand projecting from the rear bow 7 at the lower end thereof is ahorizontally extending loop 9. The frame formed by the two bows 6 and 7and the loop 9 is covered except at the front thereof by a wire fabrichood l() and a wire fabric can be secured within the loop E) so that acompartment is formed within the hood and in rear of the stack for thereception of einders, etc. Instead of providing a wire fabric within theloop 9 a plate may be used. In either event an opening l'l is formedabout which is secured a depending outlet pipe l1?. It is to be notedthat the front bow t5 of the hood is curved forward so as to overhangthe stack.

By providing a locomotive or traction engine stack with an arrester suchas herein de- I scribed a portion ol the products of combusl tion uponleaving the stack will enter the hood 1l() and the gaseous products willpass through the hood while the ciuders will be retained thereby. Aportion of the products of combustion will not enter the hood but anyciuders which may be carried upward with this portion of the escapingproducts will be driven back into the hood by the current of airestablished by the forward movement of the engine. As the entire hood isplaced back of the axis of the ring 3 it is apparent that the pressureof the wind thereagainst will always maintain the hood in position Vuponthe rear portion of the stack. If the engine is not in motion the hoodwill be maintained in proper position by any wind which may be blowing.

It will be understood that the ciuders will be dellectcd by the hoodinto the rear compartment within the device from which they will passdownward to the pipe 12. This pipe may conduct the ciuders to any pointdesired but it must necessarily be connected only to the hood so thatthe rotation of the hood will not be interfered with.

It will be seen that this device is very simple, durable and inexpensivein construe'- tion, can be readily attached to a stack and constitutesan ellcient means for collecting the cinders as they escape from thestack.

It will be noted that the hood 9 is disposed below the upper end of thestack and therefore the upper 'portion of the stack and the adjoiningpart of the hood forni a receptacle for holding the ciuders after theyhave been caught by the hood and deflectedrearwardly,

'hat is claimed is:

l. lhe combination with a stack having an annular supporting flange; ofa split ring rotatably mounted upon the stack and bearing upon the(lange, a supporting bow extending from opposite portions of the ringand over the end of the stack, said bow being curved so as to overhangthe stack, a loop extending horizontally from the ring, a fabric hoodsupported by the bow and ring, said hood ovcrhanging the end of thestack and leaving opposite portions of said stack exposed, a fabricbottom upon the horizontal 1 bow, and an outlet tube extending from saidbottom, said bottom being,` disposed below f tuting a, spark receptacleand seid stack eX- the end of the stack whereby a spark reoeytendingthroughout the width, and Constiing receptacle is produced within thehood. tuting one wall, of the spark receptacle.
